Well, I cut with a wheeled cutter and got a good crackling sound and
left a groove I could feel with my fingernail. But I could sit on it
and bounce up and down and it wouldn't break. The piece of glass was
criss-crossed with grooves, because I kept trying slightly different
techniques to try to get it to break.
Finally, I gave up and asked my local hardware store to come over and
replace my window pane. I described what happened, and they said that
if it didn't break when I jumped up and down on it, it must be
So, I figured I'd throw out the sheet I had been working on, since it
was criss-crossed with scratches and I couldn't cut it anyhow. Since
it wouldn't fit in the trash, and it was already clamped to my work
table with a section overhanging, I figured I'd just hit it with
hammer to break it into pieces. I took an eight pound hammer, put on
my goggles, and whacked it. The hammer bounced off. I whacked it
harder - same thing. So I raised up that hammer and really put some
back into it. That's when the glass shattered into a zillion tiny
pieces. The entire pane shattered - even the part that was clamped
flat to the table.
So I don't know if it was safety glass or tempered glass or something
else, but I don't feel so bad about not being able to cut it.
